Because the formula and parameter for operation dew-point temperature are known, dew-point temperature process is being obtained in order to reduce
In, the operation pressure of processor 10 can also be run according to semiconductor laser in the another specific embodiment of the utility model
In the process, the calculation formula and parameter of the temperature range in working environment and humidity range and dew-point temperature, determines work
One-to-one relationship in the temperature range and humidity range of environment under each temperature and humidity with dew-point temperature, and by the correspondence

When, complicated operation is all carried out, corresponding dew-point temperature can be directly inquired, reduce the operation pressure of processor 10,
Reduce the requirement of the performance to processor 10.
Based on above-mentioned any embodiment, it is contemplated that when generally dew-point temperature is relatively high, it may be possible to warm and humid in working environment
Caused by degree adjusting device cannot regulate and control aerial temperature and humidity well.Therefore in the another specific embodiment of the utility model,
Can also include：
The warning device 14 being connected with the processor 10；
The warning device 14 is used for when the processor 10 judges that the dew-point temperature is more than preset temperature threshold, hair
Go out alarm, by sending out alarm to staff, the danger for existing in staff's equipment and condensing is reminded, so as to the people that works
Member is checked and is regulated and controled to relevant device.
In view of the normal working temperature of semiconductor laser therefore, is adjusted according to dew-point temperature at 5 DEG C~40 DEG C
When the cryogenic temperature of refrigerator, it is also necessary to consider temperature range when semiconductor laser can work normally.For this this practicality
In novel another specific embodiment, warning device 14 includes humiture warning device；
When processor 10 judge dew-point temperature be more than the first preset temperature threshold and be not more than the second preset temperature threshold, and
When the cryogenic temperature for controlling the refrigerating plant 12 is 1 DEG C of temperature higher than the dew-point temperature.Illustrate to deposit in the working environment
In moisture condensation risk, therefore, which is issued by humiture alarm；Wherein, first preset temperature threshold is small
In second preset temperature threshold.
It should be noted that because at 20 DEG C, dew condensation phenomenon can all occur in Chinese overwhelming majority area, freeze at this time
The cryogenic temperature of device is that heating is adjusted to the adjusting of temperature in working environment.It is also contemplated that the heat in cryogenic temperature and environment passes
It passs that there are certain temperature difference, therefore, the setting of cryogenic temperature generally should be not less than 23 DEG C, when the temperature in working environment is less than
At 23 DEG C, it can prevent temperature from continuing reduction and dew condensation phenomenon occur.
The normal working temperature range of semiconductor laser is not above 40 DEG C, for the sake of security, will generally need by
The temperature of semiconductor laser is controlled at 35 DEG C hereinafter, the temperature tune of the cryogenic temperature noise spectra of semiconductor lasers of refrigerating plant at this time
Section is that cooling is adjusted, it also is contemplated that the temperature difference problem transmitted to heat, it is 32 DEG C that cryogenic temperature, which should be not higher than,.
Because dew-point temperature only in working environment is higher than 23 DEG C, and when cryogenic temperature is less than dew-point temperature, refrigeration temperature
Degree is likely to cause to generate dew condensation phenomenon to the adjusting of refrigerating plant surrounding air, just needs suitably to increase cryogenic temperature extremely at this time
More than dew-point temperature.So in the present embodiment, the first preset temperature threshold can be set as 23 DEG C, once work dew point
Temperature is higher than first preset temperature threshold, it is necessary to suitably increase cryogenic temperature.Because of the best effort of semiconductor laser
Temperature is closer to 20 DEG C, so cryogenic temperature will be while higher than dew-point temperature, closest to the best of semiconductor laser
Operating temperature.So when dew-point temperature is more than the first preset temperature threshold, cryogenic temperature can be increased to compare dew-point temperature
0.5 DEG C high~2 DEG C of temperature, and more preferably embodiment is that cryogenic temperature is increased to 1 DEG C of temperature higher than dew-point temperature
Degree, while thinking that staff sends out humiture alarm, it reminds the humiture in staff's working environment higher, causes to reveal
Point temperature drift can remind staff to increase the wet strength of removing in working environment, and check to the temperature tune in air
Save equipment whether failure.
In addition, in order to ensure that semiconductor laser can work normally, the maximum temperature of cryogenic temperature preferably not more than
32 DEG C, therefore, when only dew-point temperature is no more than 32 DEG C, cryogenic temperature could be increased to 1 DEG C of temperature higher than dew-point temperature,
So can 32 DEG C be set as the second preset temperature threshold.
In conclusion the first preset temperature threshold and the second preset temperature threshold disclosed in the present embodiment are only this
A kind of specific embodiment of utility model, the first preset temperature threshold and the second preset temperature threshold in the utility model are not
23 DEG C and 32 DEG C are only limitted to, adjustment appropriate can be done according to actual conditions.
In view of when dew-point temperature is more than the second preset temperature, system cannot be reduced by adjusting cryogenic temperature again
Cold temperature is affected to generating moisture condensation in working environment.At this point, occurring the possibility bigger to condense in working environment, it is necessary to
Staff is reminded, is highly desirable to have checked the equipment of the humiture in regulation and control working environment, therefore for above-mentioned
Embodiment can be further improved, specifically, warning device 14 includes moisture condensation warning device；
When processor 10 judges that dew-point temperature is more than the second preset temperature threshold, and the cryogenic temperature of refrigerating plant 12 is controlled
For the first default cryogenic temperature when, and send out moisture condensation alarm, so as to remind user check temperature and humidity adjustment equipment.
It should be noted that the first default cryogenic temperature refers to the temperature that temperature is slightly above the second preset temperature threshold, this
A preferred first default cryogenic temperature is 32.5 DEG C in embodiment.
Because in the work environment, processing has a refrigerating plant that noise spectra of semiconductor lasers is adjusted into trip temperature, also with pair
The temperature and humidity adjustment equipment, such as air-conditioning, dehumidifier etc. that temperature and humidity in air is adjusted, when dew-point temperature reaches
When two preset temperature thresholds, it is more likely that humiture shape in working environment can not be adjusted well by being exactly humiture equipment
Condition, therefore moisture condensation alarm can be sent out, to remind staff to check whether temperature and humidity adjustment equipment works normally.
In addition, it is contemplated that in certain extreme cases, if dew-point temperature is more much higher than the second preset temperature threshold, example
Such as, the second preset temperature threshold is 32 DEG C, and dew-point temperature reaches 37 DEG C or more, then illustrating that temperature and humidity adjustment equipment is likely to
There is catastrophe failure, moisture condensation warning device can send out serious moisture condensation alarm to staff, so that staff ties up in time
It repaiies.
In addition, it is necessary to which explanation is controlled if processor 10 judges that dew-point temperature is not more than the first preset temperature threshold
The cryogenic temperature of refrigerating plant 12 processed is the second default cryogenic temperature.It, can be with because dew-point temperature is not higher than the first preset temperature
It is that humiture in working environment is to maintain always the suitable state of comparison so that dew-point temperature is relatively low, then refrigerating plant 12
Cryogenic temperature be typically also be arranged in normal cryogenic temperature, that is to say the second default cryogenic temperature, can be 23 DEG C.But also
It is likely that dew-point temperature before is relatively high, be due to dehumidification equipment or temperature control equipment to the humiture in air into
Adjusting is gone so that dew-point temperature decreases compared to the dew-point temperature of last moment, and the system of refrigerating plant 12 before
Cold temperature is raised to more than normal cryogenic temperature, then the cryogenic temperature can be adjusted to normal cryogenic temperature at this time,
I.e. second default cryogenic temperature.
Based on above-mentioned any embodiment, it is contemplated that because dew-point temperature is determined by two aspect factor of temperature and humidity
, and when semiconductor laser normal work, not only the moisture condensation situation in environment is required, also has one to temperature and humidity
Fixed requirement.Therefore, in actual application, it is understood that there may be the temperature in working environment has had exceeded semiconductor laser
The temperature range that can be worked normally, and due in air humidity it is extremely low, cause dew-point temperature and be no more than preset temperature threshold,
Eventually leading to semiconductor laser can not work normally.
For this purpose, in the another specific embodiment of the utility model, it can also further limit, specifically include：Alarm dress
It includes temperature alarming device to set 14；
When processor 10 judges that the temperature at current time exceeds preset temperature range, then temperature alarming is sent out, so as to work
Make personnel's degree temperature control equipment to check.
Because the temperature range of semiconductor laser normal work is 5 DEG C~40 DEG C, in order to avoid semiconductor laser is straight
It can just alarm to breaking down, preset temperature range can be set in a temperature more smaller than the temperature range of normal work
Can also be other temperature ranges such as 10 DEG C~35 DEG C in range, as long as in 5 DEG C~40 DEG C temperature ranges.
As described above, semiconductor laser works normally, it is also necessary in suitable humidity environment.Therefore, based on
On the basis of above-mentioned any embodiment, in the another specific embodiment of the utility model, it can also be further improved, it is specific to wrap
It includes：Warning device 14 includes humidity alarm device
When processor 10 judges that the humidity at current time is more than default humidity threshold, then humidity alarm is sent out, so as to work
Make personnel to check dehumidification equipment.
The normal operation ambient humidity of general semiconductor laser should be less than 65%, then, it can incite somebody to action in the present embodiment
Preset temperature threshold is set smaller than 65% threshold value.
